Drag and drop an answer to each box to correctly complete the derivation of a formula for the area of a sector of
a circle.
Suppose a sector of a circle with radius r has a central angle of 0. Since a sector is a fraction of a full
circle, the ratio of a sector's area A to the circle's area is equal to the ratio of the central angle to the
measure of a
rotation of the circle. A full rotation of a circle is 21 radians. This
proportion can be written as 4 = 1
Multiply both sides by arra and simplify to get
where
is the measure of the central angle of the sector and r is the radius of the
circle.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
